Latest Patents
One of Saitoh's latest patents is a disk device and data reassignment method. This invention describes a disk device and a method for reassigning data areas, such as sectors, to minimize the reduction in data transfer rates when alternate data areas are used to replace defective areas. The disk device utilizes multiple data zones with spare areas allocated in each zone. An alternate area is allocated in the spare area where the error occurs and at an angular position offset more than a predetermined angle from the position of the data in which the error occurs. This offset allows the device to seek the alternate area, read it, and return to the area following the defective area within a single rotation of the disk. Another significant patent is a storage device and error recovery method that executes a plurality of error recovery routines divided into groups. When an error occurs, specific routines are selected from these groups based on the error type, enhancing the error recovery rate during the early stages of the recovery procedure.
